. . . . . . nucleotide is not present in $RNA$.

Which nitrogen atom of a purine base is bonded with the furanose sugar to form a nucleoside?

Which of the following represents the simplified version of a nucleoside?

The $AT/GC$ ratio in human beings is (where $A = \text{adenine}$,$T = \text{thymine}$,$G = \text{guanine}$,$C = \text{cytosine}$)

Given below are two statements:
Assertion $(A)$: Hydrolysis of $DNA$ does not form equal number of $A$ and $T$; $G$ and $C$.
Reason $(R)$: In $DNA$,adenine forms hydrogen bonds with thymine and cytosine forms hydrogen bonds with guanine.
The correct answer is:

$RNA$ is different from $DNA$ because $RNA$ contains
